Patent attributes
A visor face shield device is configured to be worn on a user's head to provide a transparent barrier in front the user's face. The visor face shield device has a bill that extends forward from a portion that contacts the wearer's forehead, and the transparent barrier extends down from the outer periphery of the bill. On the bill are one or more fan units, including multi-stage air filter elements, that blow air through the bill into the space between the wearer's face and the transparent barrier. Under the fan unit(s) are louvers or equivalent air directing structures that direct air. The louvers can be configured to blow air both in the direct of the wearer's face and in the direction of the transparent barrier. The device can include controls to move louvers, or independently control multiple fan units. As configured, the visor device allows a wearer who is wearing a face mask and eyewear under the visor device to control air flow to prevent fogging of the transparent barrier and the wearer's eyewear, as well as provide comfort for the wearer.
